SANTA CLARA — Two people were injured — one of them a park employee — Friday night in an apparent roller coaster accident at Great America, according to authorities and media reports.

A park worker was apparently struck in the head by a rider at 8:15 p.m. on the Flight Deck roller coaster, according to a report by ABC7. The worker suffered traumatic injuries, while one rider suffered a hand injury.

Calls to the Santa Clara Fire Department were not immediately returned.

The Flight Deck is a Swedish-made inverted roller coaster ride where riders” legs hang freely. The roller coaster debuted at the park in 1993 as Top Gun.

In 1998, a Hayward man was killed after he tried to retrieve a hat he lost while on the ride.
